A blow molding machine with air conditioning that while minimizing the introduction rate of outside air maintains constant temperature in a plant building and the interior of a blow molding machine and production of a bottle as a final configuration with stability in its measurement value. The machine is constructed so that air for biaxially stretching blow molding together with hot air of heating zone and internal air of a plant building is suctioned by suction chamber, filtered by primary filter and secondary filter into clean air, brought into heat exchange with primary cooling coil, fed under pressure by air blower and released through low-temperature duct into the interior of the plant building. Further, a housing on its side face is provided with vent to allow reflux of the clean air released into the interior of the plant building and flow into the heating zone and blow zone.
A blow molding machine with air conditioning, comprising a heating zone where a preform is heated, a blow zone where the preform is biaxially stretch-blown, and suction means which is provided in at least said heating zone and discharges out heated air from the interior of said heating zone, wherein air in said heating zone is suctioned by said suction means and filtered into clean air, the temperature of the air is adjusted to a constant temperature/temperature range, whereupon the air is discharged into a factory building in which said blow molding machine is installed, and is recirculated to said heating zone and said blow zone, to thereby keep constant respective atmosphere temperatures in said factory building and said zones.
